CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 USC § 119(a) of Korean Patent Application No. 10-2021-0018691, filed on Feb. 9, 2021 in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes.

BACKGROUND 1. Technical Field

The present disclosure relates to a steering wheel of a smart mobility vehicle, and a steering apparatus including the same.

2. Related Art

A smart mobility is an intellectualized means of transportation. Since the smart mobility uses electricity as a main power source, the smart mobility generates no exhaust gas. Thus, much attention is being paid to the smart mobility as a next generation means of transportation.

In the related art, however, when an image is displayed at fixed position, an occupant's view may be blocked depending on the build/position of the occupant (including a driver and a passenger). In this case, the occupant may not normally recognize information displayed in the image.

Furthermore, since a steering wheel which is adjusted in a top-to-bottom direction according to the build/position of the occupant has a limit within a fixed cockpit, there are difficulties in improving driving convenience only by adjusting the steering wheel.

Hereafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Projection Device of Smart Mobility Vehicle (FIGS. 1 to 10 )

FIGS. 1 to 10 illustrate a projection device of a smart mobility vehicle in accordance with an embodiment of the present disclosure.

Referring to FIGS. 1 to 10 , the projection device of the smart mobility vehicle basically includes a windshield 130 and a projector 140.

The windshield 130 may include an internal display area and an external display area, which are divided and applied. The internal display area displays an image toward the inside of a vehicle 10, and the external display area displays an image toward the outside of the vehicle 10.

The internal display area may be located at a higher level than the external display area, and has an internal display 110 located therein.

The external display area may be located at a lower level than the internal display area, and located in an air vent area (not illustrated) located at the front of an existing bumper (not illustrated). Such an external display area has an external display 120 located thereon.

The internal and external displays 110 and 120 each have a separate power application path.

The projector 140 projects an image for each function, containing vehicle driving information, toward the windshield 130.

The projector 140 is configured as a short focal length projector which projects images toward the internal and external display areas.

The projector 140 is disposed around the floor of the vehicle, where an FOV (Field Of View) area can be secured, and has a projection light path between the internal and external display areas.

For another example, the projector 140 may be disposed in a cockpit of the vehicle, where an FOV area can be secured, and have a projection light path between the internal and external display areas. For still another example, a projector 140′ may be disposed on the inner surface of the roof of the vehicle, where the field of view can be secured, and have a projection light path between the internal and external display areas.

At this time, a reflecting mirror capable of adjusting the position of an image projected onto the internal/external display area may be disposed on the projection light path.

The projector 140 may have a projection light path between the internal and external display areas by adjusting the position of each front projection area.

Here, an empty space which does not interfere with a peripheral object may be formed around the projection light path.

The projector 140 may selectively adjust the projection area, such that an image displayed on the external display area is not seen by an occupant.

In other words, in order to promote the convenience and stability of the occupant's driving, an image of the external display 120 except an image of the internal display 110, which is required for the occupant, may be blocked inside the vehicle.

The projection device of the smart mobility vehicle in accordance with another embodiment of the present disclosure includes an internal display 110, an external display 120 and a projector 140.

The internal display 110 displays an image toward a driver seat.

The external display 120 displays an image toward the outside of a vehicle 10.

The projector 140 emits beam toward the internal and external displays 110 and 120 such that an image for each function, containing vehicle driving information, is displayed on the internal and external displays 110 and 120.

The projector 140 may divide a screen for each function by projecting the image for each function, containing the vehicle driving information, onto the internal and external displays 110 and 120 at the same time.

The internal and external displays 110 and 120 may each have an electrochromic film 131 whose transparency can be adjusted when power is applied thereto.

The electrochromic film 131 includes a first film 131 a attached to the inner surface of a windshield and a second film 131 b attached to the inner surface of the first film 131 a.

At this time, the first film 131 a may be an SPD (Suspended Particle Devices) film having a dark color, and the second film 131 b may be a PDLC (Polymer Dispersed Liquid Crystal) film having a relatively brighter color than the first film 131 a.

The first film 131 a may be switched to a black color when the power supply is turned off, and switched to a transparent color when the power supply is turned on. At this time, the transparent color may differ depending on the tinting concentration of the vehicle.

The second film 131 b may be switched to an opaque white color when the power supply is turned off, and switched to a transparent color when the power supply is turned on.

Since information is acquired from an image formed on the surface of the internal display 110, external light needs to be blocked in order to secure visibility. On the other hand, since an image formed on the surface of the external display 120 needs to be checked from the outside, the external area of the external display 120 needs to be exposed.

When the color of the windshield 130 is changed by electricity applied thereto, the voltage/current of the applied electricity may be adjusted to gradually apply the change between the transparent state and the opaque state, in order to improve the emotional quality. In this case, the effect for a UI (User Interface) may be implemented. Furthermore, when the state of the windshield 130 needs to be switched in different situations, the state of the windshield 130 can be switched immediately.

Cockpit Moving Structure of Smart Mobility Vehicle (FIGS. 11 to 20 )

FIG. 11 schematically illustrates a cockpit moving structure of the smart mobility vehicle in accordance with the embodiment of the present disclosure.

Referring to FIG. 11 , the cockpit moving structure is a component of a next-generation smart mobility vehicle, in which a driver seat is configured as a bench seat and the positions of components within the cockpit can be switched.

Such a cockpit moving structure includes a console 210, a cockpit module 220 and a steering wheel 230.

The console 210 is disposed in a dashboard area at the inner front of the vehicle.

The cockpit module 220 is disposed at the top of the console 210, and can be moved in a top-to-bottom direction.

The steering wheel 230 is connected to the rear of the cockpit module 220, and can be moved from side to side in the longitudinal direction of the cockpit module 220. The longitudinal direction of the cockpit module 220 indicates a side-to-side length.

FIGS. 12 to 14 illustrate an example in which the cockpit module and the steering wheel are moved, in the cockpit moving structure of the smart mobility vehicle in accordance with the embodiment of the present disclosure.

Referring to FIGS. 12 to 14 , the cockpit moving structure of the smart mobility vehicle 10 in accordance with the embodiment of the present disclosure has a configuration in which the cockpit module 220 connected to the console 210 can be moved in the top-to-bottom direction according to the body type of an occupant as illustrated in FIG. 12 .

At this time, the console 210 is tilted at a predetermined angle toward an engine room (not illustrated).

When the cockpit module 220 is moved upward, a seating posture space for the occupant and an available space for the occupant's hand reach may be increased through a tilt-up and tele-in operation of moving the cockpit module 220 to the front (toward the engine room) and rotating the cockpit module 220 upward.

When the cockpit module 220 is moved downward, the seating posture space for the occupant and the available space for the occupant's hand reach may be decreased through a tilt-down and tele-out operation of moving the cockpit module 220 to the rear (toward the occupant) and rotating the cockpit module 220 downward.

FIGS. 13 and 14 illustrate that the position of the cockpit module 220 is moved upward when the cockpit module 220 faces forward, and moved downward when the cockpit module 220 faces backward. However, this is only an example for description, and the present disclosure is not limited to such a structural mechanism. The position of the cockpit module 220 may be adjusted while the cockpit module 220 is unlocked from the console 210.

FIGS. 15 to 17 schematically illustrate the cockpit moving structure of the smart mobility vehicle in accordance with the embodiment of the present disclosure, and FIG. 18A, 18B illustrate an example in which a portion A marked in FIG. 17 is unlocked.

Referring to FIGS. 15 to 18B, the console 210 includes a housing 211, a slider 212, an elastic member 213, a locking member 214, a lever 215, a guide bracket 216 and a holder 217.

The housing 211 forms the body of the console 210, and has a guide hole 211 a disposed at the inner top thereof and formed as a long hole in the top-to-bottom direction. Such a housing 211 is formed with a bending structure which is inclined upward toward the front, and has a structural characteristic to guide the upward/downward movement of the cockpit module 220.

The slider 212 may be slid upward and downward in the guide hole 211 a of the housing 211. Such a slider 212 is structurally connected to the cockpit module 220.

The elastic member 213 is disposed at the bottom of the slider 212. When the slider 212 is unlocked, the elastic member 213 serves to compensate for the weight of the cockpit module 220 in order to prevent the cockpit module 220 from drooping due to the weight thereof. Such an elastic member 213 may be any one of an air spring, a torsion spring, a compression spring and a tension spring.

The locking member 214 limits the movement of the slider 212 by locking and unlocking the slider 212. When the lever 215 is pulled backward, the locking member 214 may be moved to the outside in a lateral direction by a compression spring 214 a located on the inside in the lateral direction, and may unlock the slider 212.

The lever 215 has a hand grip structure, and is connected to the rear of the slider 212. Such a lever 215 is interlocked with the slider 212 and the locking member 214 through a reciprocal link structure. For example, when the lever 215 is pulled to the rear of the slider 212, the lever 215 may unlock the slider 212 locked by the locking member 214.

The lever 215 may be disposed at a position where the lever 215 does not interfere with the steering wheel (230 of FIG. 14 ), when the steering wheel 230 is moved from side to side.

The guide bracket 216 guides the slider 212 to slide upward/downward. The slider 212 is movably connected to the top of the guide bracket 216, and the elastic member 213 is fixed to the bottom of the guide bracket 216. Such a guide bracket 216 may have an L-shaped cross-sectional structure.

The holder 217 is disposed at the bottom of the guide bracket 216, and serves as a support of the guide bracket 216. Such a holder 217 may have an upper portion which is inclined downward toward the front.

As illustrated in FIGS. 17 and 18 , a lifting and lowering mechanism of the cockpit module 220 which is lifted and lowered by the operation of the lever 215 is operated as follows.

When an occupant pulls the lever 215 to the rear (toward the occupant), one side of a first lever 215 b interlocked with the lever 215 is rotated about a rotating shaft 215 c such that the position thereof is switched to the rear with the lever 215, and the other side of the first lever 215 b is rotated about the rotating shaft 215 c such that the position thereof is switched to the front.

One side of a second lever 215 d is interlocked with the other side of the first lever 215 b, and moved forward. At this time, a section of the second lever 215 d on the other side thereof maintains the state in which the locking member 214 locks the slider 212. Then, when the one side of the second lever 215 d is moved forward, the section of the second lever 215 d on the other side thereof is moved forward in connection with the forward movement of the one side of the second lever 215 d. Through this process, the locking member 214 is moved to the outside in the lateral direction by the compression spring 214 a located on the inside in the lateral direction, and unlocks the slider 212.

When the occupant pushes the lever 215 forward while the slider 212 is unlocked, the position of the cockpit module 220 is moved upward toward the front. On the other hand, when the occupant pulls the lever 215 backward, the position of the cockpit module 220 is moved downward toward the rear.

At this time, when the lever 215 enters a preset section at the rear, the locking member 214 of the cockpit moving structure can lock the slider 212 again.

FIGS. 19 to 20 illustrate an example in which the cockpit module is moved in the top-to-bottom direction through a rotation operation, in the cockpit moving structure of the smart mobility vehicle in accordance with the embodiment of the present disclosure.

According to the cockpit moving structure of the smart mobility vehicle, illustrated in FIGS. 19 and 20 , an occupant may move the cockpit module (220 of FIG. 11 ) upward and downward through a manual rotation method, unlike the embodiment described with reference to FIGS. 15 to 18 .

A console 210′ includes a lever 215′ which is disposed on either side at the top thereof, and rotated in the front-to-rear direction so as to lift/lower the cockpit module (220 in FIG. 11 ).

The console 210′ may additionally include a housing 211′, a slider 212′, a rail 213′, a worm gear 214′, a spur gear 216′, a circular holder 217′ and a rack gear 218′.

The housing 211′ is a basic frame having a housing space therein.

The rail 213′ is disposed at the inner top of the housing 211′ along the top-to-bottom length thereof. At this time, the rail 213′ may guide the lifting/lowering path of the slider 212′, and the slider 212′ may be lifted/lowered on the path of the rail 213′.

The worm gear 214′ can be rotated in connection with the lever 215′. Such a worm gear 214′ may be set to a self locking mode for preventing reverse rotation thereof.

The spur gear 216′ is located at the top of the worm gear 214′, and rotated in connection with the worm gear 214′.

The circular holder 217′ may have a structure capable of seating the lever 215′ thereon, and the lever 215′ may be hidden through a rotating or sliding operation thereof.

The rack gear 218′ may be disposed on a side surface of the spur gear 216′, such that the position thereof can be adjusted in the top-to-bottom direction by the rotation of the spur gear 216′.

Steering Device of Smart Mobility Vehicle (FIGS. 21 to 30 )

FIGS. 21 and 22 schematically illustrate a steering wheel part whose position can be switched between a driver seat and a passenger seat, in a steering device of the smart mobility vehicle in accordance with the embodiment of the present disclosure.

Referring to FIGS. 21 and 22 , the steering device of the smart mobility vehicle includes a cockpit module 310, a steering wheel part 320 and a locking part 330.

The cockpit module 310 is located in front of the driver seat and the passenger seat within the vehicle. Such a cockpit module 310 includes a rail bracket 311 including a first flat section 311 a (?), a second flat section 311 c (?), and a locking section 311 b (?, ? and ?). The first and second flat sections 311 a and 311 c are located in front of the driver seat and the passenger seat, respectively, and the locking section 311 b is curved upward and serves to connect the first and second flat sections 311 a and 311 c.

The locking section 311 b has first and second inclined sections ? and ? formed at both ends thereof, and the first and second inclined sections ? and ? are engaged with the steering wheel part 320 so as to restrict the rotation of the steering wheel part 320.

The steering wheel part 320 is connected to the cockpit module 310, such that the position thereof can be switched toward the driver seat or the passenger seat in the longitudinal direction of the cockpit module 310.

When the steering wheel part 320 passes through the locking section 311 b (?, ?, and ?) as the position thereof is switched by a user's manipulation, the rotation of the steering wheel part 320 needs to be restricted. This is in order to improve the driving safety of the vehicle.

The locking part 330 fixes the steering wheel part 320 according to a preset condition. The preset condition indicates optimal reference data considering the stopping and parking states of the smart mobility vehicle, information on whether the driving road corresponds to a straight section, and the driving safety.

Here, driving road determination logic monitors the road condition ahead through a radar or lidar, and determines that the steering wheel part 320 can be switched from side to side, when the corresponding road is a straight section. At this time, the steering wheel part 320 may be automatically and/or manually unlocked through the locking part 330.

FIG. 23 is a diagram schematically illustrating the steering device in the smart mobility vehicle in accordance with the embodiment of the present disclosure, FIG. 24 is a cross-sectional view taken along line B-B′ of FIG. 23 , and FIGS. 25 and 26 are diagrams each illustrating the operation relationships among the components of the steering device.

The steering wheel part 320 illustrated in FIGS. 23 to 26 can be locked or rotated through a paddle shift type of steel wire connection. The steering wheel part 320 includes a base plate 321, a casing 322, a lever 323 and a steering wheel 324.

The base plate 321 can be moved from side to side along the cockpit module 310. That is, the base plate 321 is connected so as to be movable on a plurality of rail brackets (311 of FIG. 22 ) formed in the longitudinal direction of the cockpit module 310.

The casing 322 is connected to the rear of the base plate 321 so as to be bent upward. Such a casing 322 has a connector 322 a embedded therein.

The lever 323 has a structure which is interlocked with the locking part 330, and protrudes from a part of the bottom of the casing 322.

The steering wheel 324 is connected to the rear of the casing 322.

The mechanical locking structure of the steering wheel part 320 will be described with reference to FIG. 24 . The locking part 330 includes a fixing member 331 and a wire 332. The fixing member 331 is moved upward and downward on the base plate 321, and fixes or releases the steering wheel part 320 to or from the cockpit module 310, and the wire 332 connects the fixing member 331 and the connector 322 a of the casing 322.

When the lever 323 is pulled to the rear (toward the driver seat), the connector 322 a interlocked with the lever 323 pulls the wire 332 to the rear, and the fixing member 331 connected to the wire 332 is moved upward to unlock the steering wheel part 320.

At this time, the steering wheel part 320 may be unlocked from the cockpit module 310 through an electric method using a solenoid or actuator, not the mechanical method.

For example, the steering wheel part 320 may be unlocked through a simple button operation, or unlocked according to a preset condition while connected to smart devices (e.g. portable terminals or the like) of the occupants on a driver seat and a passenger seat. The steering wheel 324 of the steering wheel part 320 may be moved by a predetermined distance through position switching, and then locked as in the initial state.

FIGS. 27 and 28 are diagrams schematically illustrating the steering wheel in the steering device of the smart mobility vehicle in accordance with the embodiment of the present disclosure.

Referring to FIGS. 27 and 28 , the steering wheel 324 includes a grip part 324 a, a function button part 324 b, a center part 324 c, a support part 324 d, a fixing part 324 e, and a hazard switch 324 f.

The steering wheel 324 may include the function button part 324 b configured in a paddle shift type so as to control the locking operation of the locking part (330 of FIG. 24 ).

The center part 324 c is steerably connected to the rear of the casing (322 of FIG. 24 ), and provides a holding space for holding a portable terminal 20. When the portable terminal 20 is held on the holding space of the center part 324 c, the portable terminal 20 may be paired with the vehicle through a vehicle control-related application installed in the portable terminal 20. Through the pairing, a user (including an occupant) may select a desired option by touching the portable terminal 20 with the steering wheel 324 held on the user's hand. The grip part 324 a is formed at either end of the center part 324 c, and provides a finger grip space of the user.

At this time, the center part 324 c is electrically (in a wired/wireless manner) connected to the smart mobility vehicle. When the portable terminal 20 is held on the holding space, the portable terminal 20 may be automatically paired with the smart mobility vehicle according to preset terminal information.

The support part 324 d is disposed at the bottom of the center part 324 c, and supports the portable terminal 20.

The fixing part 324 e is disposed between either end of the center part 324 c and the grip part 324 a, and fixes the portable terminal 20. At this time, the fixing part 324 e may be formed in a hinge-connected clamp type, or have a separate buffer member (not illustrated) disposed in a section where the fixing part 324 e comes into contact with the portable terminal 20, in order to fix the portable terminal 20.

Occupant Recognition-Based Image Display Control Device and Method (FIGS. 31 to 40 )

FIG. 31 is a diagram illustrating an occupant recognition-based image display control device in accordance with an embodiment of the present disclosure.

The occupant recognition-based image display control device in accordance with the embodiment of the present disclosure includes an input unit 410, a memory 420 and a processor 430. The input unit 410 is configured to receive occupant recognition information, the memory 420 is configured to store a program for controlling an image display within the vehicle by using the occupant recognition information, and the processor 430 is configured to execute the program. The processor 430 transmits a command signal to change a partial area of an image display area within the vehicle to an area which does not block an occupant's view, by using the occupant recognition information.

The input unit 410 receives the occupant recognition information including one or more of the eye position and the head position of an occupant.

The processor 430 transmits a command signal for lowering the partial area by using the occupant recognition information.

The processor 430 transmits a driving command signal to an actuator connected to a reflecting mirror, and rotates the reflecting mirror such that a projection image based on image contents for a passenger is formed on the dashboard area.

When the difference between the eye or head positions of the driver and the passenger is out of a preset range, the processor 430 transmits the command signal to lift the partial area.

The input unit 410 receives information related to the state in which the height of a cockpit is adjusted, and the processor 430 transmits the command signal to adjust the partial area of the image display area within the vehicle by using the occupant recognition information and the information related to the state in which the height of the cockpit is adjusted.

The processor 430 transmits an electrochromic film control signal to adjust the transparency of an empty space which occurs as the partial area of the image display area within the vehicle is changed.

FIG. 32 illustrates an occupant sensing process in accordance with an embodiment of the present disclosure.

Referring to FIG. 32 , the eye position or body (head) position of an occupant is sensed by an in-vehicle monitoring device 510 such as an IR camera or ToF camera.

The processor 430 receives information on the eye position or body position of the occupant as occupant information, and transmits a display position adjustment-related command signal for the internal display in consideration of the occupant information.

The processor 430 acquires information on the occupant's height when seated (sitting height), and the eye position and the FOV of the occupant, by using the occupant information.

Furthermore, the processor 430 may receive occupant information from a separate sensor (e.g. a weight sensor mounted in a seat), and recognize whether the occupant is an adult or kid.

At this time, the processor 430 decides display position coordinate information of the internal display according to the occupant information of each occupant and transmits a command signal, or transmits a command signal for display position coordinate information of the internal display based on a preset category to which the occupant information of each occupant belongs.

For example, suppose that the position of the partial area of the display area within the vehicle is adjusted, when the eye position of a passenger A is a position A-1 (1 m in a vertical direction z from a preset reference point within the vehicle) and the eye position of a passenger B is a position B-1 (0.8 m in the vertical direction z from the preset reference point within the vehicle). Hereafter, the position adjustment will be described in detail with reference to FIGS. 7 to 9 .

For example, it is assumed that, when the eye position of a passenger corresponds to a preset position (e.g. 1 m or less in the vertical direction z from the preset reference point within the vehicle), the position of the partial area of the display area is adjusted in proportion to the eye position. In this case, a position adjustment reference value may be set to 5 cm.

At this time, the center position of the above-described partial area in the case of the passenger A can be lifted by 5 cm from the existing display position, and the center position of the partial area in the case of the passenger B can be lifted by 6 cm from the existing display position.

For another example, when a first classification in which the center position of the partial area is lifted by 5 cm from the display position in the case that the eye position of the passenger is 1 m or less in the vertical direction z from the preset reference point within the vehicle and a second classification in which the center position of the partial area is lifted by 7 cm from the display position in the case that the eye position of the passenger is 0.7 m or less in the vertical direction z from the preset reference point within the vehicle are set according to the eye position of the passenger, the processor 430 determines that both of the passengers A and B correspond to the first classification, and lifts the center position of the partial area by 5 cm from the existing display position.

The processor 430 transmits a command signal to adjust the display position of the internal display area in overall consideration of the height adjustment information of the cockpit and the occupant information.

That is, the processor 430 determines whether the occupant's view is blocked, by using the occupant information and the height adjustment information of the cockpit, and transmits a command signal to adjust the display position of the partial area of the internal display area, according to the determination result.

The projector having received the command signal adjusts the display position of the partial area of the internal display area, or the actuator having received the command signal drives (rotates and unfolds) the reflecting mirror to adjust the area on which a projection image is formed.

Furthermore, in order to prevent the driver's view from being blocked as the display position of image contents is adjusted, the processor 430 sets a position adjustment limit value for the partial area of the internal display area, and transmits a command signal related to the display position adjustment.

For example, the height of the partial area of the internal display area in front of the passenger seat is set to a value that cannot rise to a preset limit value (e.g. 20 cm) or more.

FIGS. 33 to 39 illustrate that the position of an image is moved, in the smart mobility vehicle in accordance with the embodiment of the present disclosure

FIG. 33A illustrates a situation in which a driver is seated on the left front seat of the vehicle, and a passenger (adult) is seated on the right front seat of the vehicle.

FIG. 33B illustrates a situation in which a driver is seated on the left front seat of the vehicle, and a passenger (kid) is seated on the right front seat of the vehicle.

FIG. 33C illustrates a situation in which a driver is seated on the right front seat of the vehicle, and a passenger (kid) is seated on the left front seat of the vehicle.

FIG. 33A illustrates the occupants' views and a situation in which the dashboard is disposed over the floor within the vehicle, the cockpit is disposed over the dashboard, and image contents are displayed on a preset area (internal display area) within the windshield.

At this time, the internal display area is divided into a preset number of partial areas (e.g. three areas in FIG. 33A, 33B, 33C), and the cockpit has an adjustable height.

Suppose that the internal display area is divided into a first area (cluster information display), a second area (navigation information display) and a third area (image contents display for passenger) from the front of the driver seat toward the passenger seat.

FIGS. 33B and 33C illustrate a situation in which an adult is seated on the driver seat, and a kid (short person) is seated on the passenger seat.

As described above, it is assumed that the cockpit has an adjustable height, and the projection area and the image position have been adjusted on the basis of the driver.

At this time, the processor 430 transmits a command signal to lower the display position of image contents in the third area in consideration of the cockpit position information and the occupant information, such that the image contents of the third area are displayed on a partial area of the dashboard area. Thus, the kid as a passenger can easily watch the image contents of the third area at the adjusted position of the internal display area.

At this time, as will be described below, the processor 430 may transmit a command signal to the actuator which changes the angle of the reflecting mirror, and control the projector to project the image contents onto the surface of an internal trim panel, such that the kid seated on the passenger seat can check the image contents.

This process uses the principle that the display area is divided into the internal display area and the external display area, and an image projected from the inside is formed on the surface (display panel) such that the image contents can be checked from the opposite side (passenger position).

As illustrated in FIGS. 33B and 33C, the processor 430 may transmit a control signal to the electrochromic film of the windshield to change the transparency of an area whose position has been moved so that the image contents for a passenger no longer needs to be displayed, thereby additionally securing visibility for the outside.

The image contents for a passenger and the size of the image contents for a passenger as well as the position of the image contents for a passenger can be changed, and each of the display areas can be independently controlled.

In accordance with the embodiment of the present disclosure, the size of the initial projection image can be adjusted, and the contents can be changed through mirroring or independent screen configuration.

FIG. 34A illustrates a default field of view and a projection position, and FIG. 34B illustrates a change in projection position when a kid is seated on the passenger seat.

The reflecting mirror is provided as a pair of reflecting mirrors 530 a and 530 b. This configuration considers that the driver seat and the passenger seat can be changed, because the steering wheel is movable from the left front seat to the right front seat of the vehicle.

That is, the reflecting mirror is provided as first and second reflecting mirrors 530 a and 530 b installed in the driver seat and the passenger seat, and configured to adjust the contents area when the driver seat is changed as the steering wheel is moved from side to side.

Referring to FIGS. 34A and 34B, a dashboard 520 has a partial surface area made of a translucent material, and maintains an opaque exterior when there is no lighting.

Referring to FIG. 34A, an internal image is projected onto the internal display area of the vehicle, and an external image (communication) is projected onto the external display area of the vehicle.

In the case of the default field of view illustrated in FIG. 34A, the angle of the second reflecting mirror 530 b is controlled in parallel to the projection direction, and the first and second reflecting mirrors 530 a and 530 b are mounted on areas which do not interfere with the internal image projection and the external image projection, respectively.

When a kid is seated on the passenger seat as illustrated in FIG. 34B, the processor 430 transmits a driving command signal to an actuator connected to the second reflecting mirror 530 b in consideration of the cockpit position adjustment information and the occupant information.

The second reflecting mirror 530 b driven by the actuator is rotated and unfolded to form a projection image of the image contents for a passenger on the dashboard 520 in front of the passenger seat (passenger seat contents image reflection).

FIG. 35A illustrates that the first and second reflecting mirrors 530 a and 530 b are separately applied to the driver seat and the passenger seat, respectively, as described above.

As illustrated in FIGS. 35B and 35C, the position of the passenger seat is decided as the steering wheel is moved to the left or right. When a passenger seated on the passenger seat is a kid, the processor 430 decides whether to display image contents for a passenger by rotating any one reflecting mirror to some extents, in consideration of the cockpit position information (the position information of the cockpit whose height has been adjusted) and the occupant information (the view information of the occupant), and transmits a driving command signal to the actuator to display the image contents.

As the actuator is driven, the second reflecting mirror 530 b is rotated (FIG. 35B) when the right front seat of the vehicle is the passenger seat, and the first reflecting mirror 530 a is rotated (FIG. 35C) when the left front seat of the vehicle is the passenger seat.

Referring to FIGS. 36A to 36D, a reflecting mirror 530 in accordance with the embodiment of the present disclosure is disposed on a sliding and rotating bar 540 which can be rotated and moved straight from side to side, and located at the opposite position of the steering wheel.

That is, when the steering wheel is disposed at the left front seat of the vehicle as illustrated in FIG. 36A, the reflecting mirror 530 is located at the right front seat of the vehicle, and when the steering wheel is moved to the right front seat of the vehicle as illustrated in FIG. 36B, the reflecting mirror 530 is moved to the left front seat of the vehicle by the sliding and rotating bar 540.

When a kid is seated on the passenger seat as illustrated in FIGS. 36C and 36D, the processor 430 transmits a driving command signal to rotate the reflecting mirror 530 by using the cockpit position information and the occupant information, and displays the image contents for a passenger on the dashboard as described above.

FIG. 37A illustrates that a driver and a passenger (adult), who have a similar eye height, are seated in the vehicle, FIG. 37B illustrates that a driver and a passenger who is taller than the driver are seated in the vehicle, and FIG. 37C illustrates that a driver and a passenger who is shorter than the driver are seated in the vehicle.

Referring to FIGS. 37A and 37B, when the difference between the eye positions or head positions of the driver and the passenger falls within a preset range, the internal display area is maintained.

Referring to FIG. 37C, when the passenger is shorter than the driver such that the difference between the eye positions or head positions of the driver and the passenger is out of the preset range, the position of a contents display area for a passenger in the internal display area is adjusted.

In accordance with the embodiment of the present disclosure, when the position of the cockpit having an adjustable height is changed to a higher position than the existing position thereof because a tall driver is seated in the vehicle, the display position of the internal display area is moved to a higher position than the existing position thereof. Thus, since the view of the passenger shorter than the driver is blocked with respect to the contents display area for a passenger, the processor 430 transmits a command signal to lift the contents display area for a passenger.

That is, when the passenger is shorter than the driver such that the third area is blocked by the cockpit, the processor 430 transmits the control command signal to lift the display area of the third area.

At this time, as described above with reference to FIGS. 33B and 33C, the processor 430 transmits the control signal to the electrochromic film of the windshield, such that the color of the area on which the image contents for a passenger are no longer displayed due to the position movement is changed to a transparent color, thereby additionally securing the visibility for the outside.

FIG. 38A is a front view illustrating the positions of the first and second reflecting mirrors 530 a and 530 b. FIG. 38B illustrates that the position of the windshield and the image area of the dashboard cannot be checked from a passenger's view due to an image blocking area.

That is, when the image contents for a passenger are displayed on the third area covered by the cockpit because the passenger is shorter than the driver, the third area is partially lifted, and the image contents are lifted and displayed.

At this time, as illustrated in FIG. 38C, the second reflecting mirror 530 b is not rotated but fixed, and only the image area (third area) is adjusted to change and display image contents, such that the image contents are moved to and displayed on an area where the passenger's view can be secured.

Referring to FIG. 39A, an electrochromic film is disposed on the image display area of a windshield 550, and an electrochromic section is subdivided so that transparent/opaque positions are adjusted in connection with contents control.

As the electrochromic film has a power application section subdivided into a plurality of sections, the concentration of each section can be adjusted, and an image is outputted onto the section whose concentration has been adjusted, through the projector or the like.

Referring to FIG. 39B, when the position of a partial area of a projection image is moved within the windshield as described above, the partial area may be changed to an empty space and become transparent to secure the visibility to the outside.

FIG. 40 is a diagram illustrating an occupant recognition-based image display control method in accordance with an embodiment of the present disclosure.

The occupant recognition-based image display control method in accordance with the embodiment of the present disclosure includes step S410 of receiving occupant state information of a driver and a passenger within a vehicle, step S420 of adjusting a reflecting mirror by using the occupant state information, or adjusting the display position of a display area within the vehicle, and step S430 of displaying image contents at the decided position.

In step S410, the occupant state information including at least any one of the eye positions and the head positions of the driver and the passenger is received.

In step S420, a command signal for adjusting the reflecting mirror is transmitted to lower a partial area of the display area within the vehicle by using the occupant state information.

In step S430, as the reflecting mirror is rotated, a projection image based on image contents for a passenger is displayed on a dashboard area.

In step S420, the display position of the partial area of the display area within the vehicle is lifted to an area where the passenger's view is not blocked, on the basis of the occupant state information.

In step S410, adjustment information on a cockpit having an adjustable height is further received. In step S420, the display position of the display area within the vehicle is adjusted on the basis of the adjustment information and the occupant state information.
